opinion thing really makes outstanding model neat little panel lines cowl lines rivets etc procedure completely finish model color apply decals spray whole thing flat clear flat finish makes nice tooth ink adhere use Rapidograph pen several good drafting pens market cheap like can buy just pen couple different size nibs sure use draft ing inkwriting ink opaque enough After have gotten lines want watch sweaty hands spray coat clear flat clear cant seal inkit too porous Finish coat flat clear am assuming first stunt model wont tell fly Like model will have trimmed own style flight aware lighter model will have less line tension need line rake heavier will like way model pops around square maneuvers August1975 69 ATTENTION HOBBY SHOPS can make money selling Model Aviation magazine
